This machine is designed to label` pails 10 of varnish, paint or other material in which eachv `pail -isprovided with a bail 11.` It

view on the line will be noticed that these hails necessitate a pair of opposite projections 12 near the i' is to be operated by a niotor, and it is also provided with a suction producing machine (not shown) operated by the same power for a purpose to be described hereinafter.. `The power is Vreceived either frein the inotor, or from a pulley elsewhere, on a pulley 15 or other Wheel, which through a pinion 16 drives a gear 17 loose on a shaft 1S. This shaft is positively iixed in the fran1el"13 and cannot rotate.

The gear `17 is provided with a hub` 19 fixed thereon which has a notch 20 in its circumference. Rotatable on the stationary shafti18 is a skeleton drain comprising a pair of discs 21. These `discs` are connected across by bars 49 and other elements andV rotate together on the stationary shaft. On one of these discs 21 is pivoted a latch 22 which engages With the notch 2O in the hub to drive the machine. When the latch engages in the notch, vthe latch is forcedv to turn With the hub 19, taking With it the disc 21 on which the latch is pivotally mounted. The latch `is 'normally swung into loclring position by a `spring 23 connected With a pin on the disc 21. The end of the latch is operated upon by the end of a lever 24, pivoted on a vertical tangent axis, which normally engages the end of the latchand holds it out of operative position as shown in Fig. 5.

Vhena receptaclel() is to be labeled, it is moved in on a horizontal support and guide 25 which has a notch 26 at one side for re ceiving the bail 11. Therefore the receptacle is` always put in in one position as indicated in Fig. l. It is pushed along the slide'25 by hand until the end of the pailor otherl to force the latch into the notch 2O the next time it comes around and thenthese partsV will rotate around onercoinplete revolution as will appear.v

This provides for the starting of themachine. When it starts a cam 30, fixed to one disc 21, has been stopped at the end of the last revolution in such position that it soon engages a roll 32 on a lever 33 Aand liftsit.

This lever 33 is fixed to a rocking arrn 3&1V

the circuniifcrences ofboth discs 21 and also` `engages a set of soft pads V36 which are located on resilient cross bars 36a arranged in curvedforniation on a support 37 that extends across thetop ofthe frame 13. These bars areicapable of yielding, being supported at their centers. y

Another action that takes place is that an arin 38 pivoted on the arin 3st is provided With a roller 39 which engages a stationary cam l0 When this arm is lifted. This brings a resilient pad l1 on the arm 38 into lcontact with the receptacle 10Vin opposition to a spring42. The cam holds it there as shown i in Fig. 2 to insure suiiicient'pressure to hold the can or receptacle against the circumferences of the discs 21. Itxvill be noted that the ends of the bail 11 and the projections in which they are mounted are provided for. @ne of theni is located in the space between the pad Li1 and the first 'pad 36and the other is `located in a notch 43 of which there are three around the circumference of one o f the discs 21. It Will be `seen that the cank or receptacle is j lifted `by the rest and brought into contact withV these pads so that `it `will necessarily roll therealong and the labels Whichhave been supplied in a manner to be described hereinafter will be smoothed out on the can or receptacle.` f

Then the receptacle reaches the end of its stroke, which is at the end'of the curvedv support 37, it Will passon a discharge chiite ist and roll out by gravity. v This discharge chute is `also provided with a notch l5 on one side for receiving` the end of the bail.

out ofuse for a period, this, discharge chute ,When the `machine is to be shipped or put llU can be swung on its pivot` 46 by lirst disf- Y connecting its strut 17 from `an angle iron 43. on the fraine and'then itwill hang substantially vertically.

The shaft 18 as stated, is held stationary lin its bearings on thefranie V1,3 and I have shown screws for holding` it in thatposition. `It has also been stated that the two discs 21 constitute a rotatable labeling druin. These discs shown in Figs. 9, 1() an-d 11 are connected across by several members including two bars 49 which are secured at their 'ends to the tivo discs `and two transverse ysuction boxes53. Between the discs and carrying the suction boxes there are tivo loose plates 50 and 50, one for each label. These plates are of arcuate shape and are designed to receive pads 52 and 52.` The suction box is connected by a port down throughtheinovable plate 50 to a suction passage. The

port between the suction box and passageis normally closed by a valve 54, butwhen this valve is opened the perforated surface communicates with thesuction passage 55, which, through a pipe 56, is connectedV to a suction device (not shown but continuously operating). i f

The suction hose 56 is connected with the source of suction through a pairof annulai chambers 75 and 76 mounted on the shaft 18 which have between them' a packing disc 7 7. This disc and the lsidesof the chambers are provided with perforations 78 to permit the air to pass through intermittently during rotation. The box containing the chamber76 is stationary while the chamber 75 rotates with the drinn. AA bracket 76a holds the member 76.

The labels are taken up, one at a time, on the outside surface of each pad 52 and this is provided with a woven fabric or feltv blanket 58 held by rods 59 at its opposite ends. The rod on the frontend is held posi tively in a recess and the rod at the rear is held under Atension by a series of springs 60 which draw the fabric taut. These springs are mounted on brackets 61 projecting in- `wardly from the plate 50. 'lhese brackets are connected by spi'iiigs'62 with arms 63 on the fixed cross piecel i9 to normally force the loose plate 50 upwardly and forwardly. On rigid arms 64: carried by this cross piece 49 and projecting inwardly is pivoted a lever 65 having a projection 66 adapted to engage a bracket 67 on'the bottom of the plate 50 and push that plate over rearwardly to wipe and smooth out the label on the can or pail. rlhe end of the leve-i 65 is provided with a roll 68 adapted to be engaged by a stationary cam 69 to operate the lever when this drum rotates to a certain position. The blanket 58 has two raised surfaces 51, one being perforated at 53. n

All this construction is repeated at another adjacent point for the purpose-of providing a similar arrangement for the other label as will be understood, but it will be necessary to describe only one. The other plate 50 is operated by a companion 'cam 69. rlhe purpose of this mechanism is to move the plate and its pad so that the label will be laid smooth on the receptacle.

Another cain 70 in fixed position is engaged by conduit 55 to operate 'the valve 54 against the resistance of its spring to open it and allow the perforations in the surface 51 to communicate with the source of suction.` ln this waythe forward end of the label is held down while the body of it is pressed against the pad 52. There is a second can?, 70al which performs the saine function for the other pad.

t will be understood that the plate 50 is provided with a projecting `edge 72 adapted a plunger 71 carried by the suction a to be received Ona ledge or plurality of lugs 72*l on each disc 21. A series of clips 7 3 are held by screws on the discs 21 to insure the holding of this plate 50 in position, but the parts are loose enough to allow some play `of .the plate 50 which is loose and is adapted to move.

'ihe hub of one disc 21 is borne upon by la stop friction strap 80. 'ihis strap, isheld at one end by a stud on the dise 21 itself .and at the other end by a stud with a spring connection 81. ln this way when the clutch is disconnected the parts will comete a stop very soon. 'lhis occurs when a revolution is coinpletedxand is caused by the tail of the latch 22 engaging under a projectionon the end of the lever 211, which of course returns to normal position as soon as the can 10 is lifted above it at the beginning ofthe rotation.

its two labels Lare to beapplied to the article or can l0 l have provided two label holders 82 and 822k rlhese are mounted on brackets tid on the frame at an angle to each other so as to deliver the labels to the two pads 52 and 52a'located adjacent "to each other on the drum and so that each one will be delivered tangentially.

exactly alike, but they are connected so that they work in the proper sequence. Thererlfhe labels'are piled up in the label holders asV indicated in fore only one of them will be described in detail.

Each label holder comprises a boxk having a bottom 85 which is mountedV on a plunger 86 that is constantly urged upwardly by a spring 87, the plungerha-ving a guide in a frame 88 which is secured on one of the brackets 84. This frame 88 has an arm ,for receiving the opposite end of the spring 87. The label holder has sides 89 thev shape of which is indicated in Fig. 1d bent over to form oneend. They cooperate with the bottoms, the bottoms of course moving .upwardly as ythe labels are exhausted; The fraineSS is provided with Van arm projecting inwardly, on which is'a stud 90 which carries a lever 91 operated by a link 92 as will appeall later. lThis lever projects between pins 93 on a slide 9.1i` which is guided in the shown in Figs. 18 and 11i or to come down on the labels as shown in Fig. 15.y Also'the bottom is adjusted with respect to an integral plate 96 by anadjusting screw 97 ,the plate 96 constituting part of the frame 88.

The top plate 95 is provided withk a pairof i clips 98 which,

lli

'mino roll is o'earedb i tace of the roll.

when the `top is lowered, bear on hooks 99 to torce them down against the top label. rlhese hooks are pointed so that they prevent the accidental displacement of the label or the taking ot two labels atV a time. Vlhese hooks constitute extensions on wire rods 100 which are guided in projections or brackets 101 on the traine 8S and are capable ot moving up and down, being normally held down by weights 102.

1t will be seen, therefore, that each time the link 02 is operated and the cover `95 is Vraised and thenlowered, the hooks 99` are iorced down onthe top label and thus held there by 'their small amount ot resistance tothe displacen ent of the label. rlhe labels are taken ed by the suction suriace 51 and the `top is `raised automatically to Airc-fe the labels and allow them to be taken olf by the action of the link 92. ln the position shown in Fig.

1.5 the spring 8T is 'tree to raise the plunger 86 and the bottoni or the label holder to press the top label upwardly, as the lever 91 has forced a ratchet plate 86a down to ree said plunger. 1n liig. 1a this ratchet plate is shown raised at one side so that it binds the plunger 86. ln referring -to the link 92j l intend to include a companion link 92u.` One is connected with each of the label `boxes and both pivotally connected with an arm 103 which isA pivoted on a stud ft on which is another arni- 105. This arin Vis connected by a link 10Gto a lever 107 which has a cani roll 108 operated by a cam 10S) which rotates with the discs 21. Theretore, `once during each rotation the label holders will be operated to raise the top and this operation will come just as the two pads 52 come to proper position for receiving the two labels from the two label bones. The two labels are taken on the drum, one beyond the other, and applied to the opposite sides oi the can 10 by the rolling motion above described.

'lfhe gumming device comprises a support 110 and a tank 111 'lor the glue. This tank can be adjusted back and torth by ahand wheel 112 and screw 112il as shown. -It is provided with a gumining roll 113 which engages the label on the pad 52. This guingearing 114 to the The tank 111, which can be shifted gear 1?.

is connected with longitudiback and forth,

nal pins 115 mounted in lugs in the support 110 so as to guide the tank in all positions. The end ot the screw 112a`is connectedwith the tank by an open bottom slot 116 so that `the tankcan be lifted oil alter the screw is turned up to bring the tank out of contact with the pins115. i f

The tank is also provided with a brush 112r at the. end bearing on the roll 113 tending to wipe or spread the glue on the sur- `This brush is made Vwith a weights so as to provide a` a `are frame 118 of doubled foversheet metal'with are delivered to the dischare'e chute Liet, the

two pads and .52 come around toward the bottom from the position shown in4 Fig.

1. The lever 2d is engaged by thelatch and the clutch disconnected, thus stopping the machine. y l y l y Y The pail or bucket is nowV placed by hand on the guide 25 in the position shown in Fig. and shoved in until its bottom engages the head 2T. rthis moves the lever 2l over as shown in 3 'the latch 22 up. This latch is then pushed so that it no longer holds S Ll downz by the spring and the next time the notch 20 cornes around the latch will swing into it. `This causes the drum composed ot the two discs 21 to start to rotate, as the latch pivoted on one o1 them.

lll/hen the pads 52 and 52a get adjacent the label holders, the cam 109 operates the link 10h and consequently the links 92. The

two links 92 actuatethe levers 91 to pull up the two tops il.

This releases the top label so that the `perforated surface 51 on each pad 52 and `52n will engage the forward ends ot' the respective labeisin proper sequence.

ylhe valves 54: will open and the leading end ot each label will be taken into Contact with the pad 52 orf52, or rather the blanket overV itand will be carried away from the label holder, spaced properly apart. 03E course at this time the hooks 99 are in engae'ement with the top label but they are held down only by the weights 102 and not by the positive action of the lever Q1 on the top plate 9o. Consequently the tore-e of the rotating drum with the suction will besuilicient to conduct the two labels away, one behind the other. `The two pads 52 and 52a are both long enoughr to carry a label spread vout thereon, so these two labels 'follow one an- `other and are both suppliedwith paste from thepaste roller 113 which has been described in connectionwith the last sheet of the drawings. New as thedrun'ieoines around so as to bring the labels up vabove the paste roller 113 the cam 30 engages the roll on the arm 33 andthe rest 35 is moved upwardly to bring the can into the position shown in Fig. 2 so that the further rotation of the drum will roll thecan alone and take up and smooth down the labels as stated above.` The barstlnl are all capable oi twisting and yielding to accommodate the pails. As theV pails are rolled along, the plates 50A and held yieldingly outwardly by springs 62 to wipe the labels on the opposite sides of the cans.- rThe air valves 54; are released by the cams and 70 in sequence also to shut off the suction. Y' f It will be seen that by this machine a 'pail of paint, varnish or any other material, having a bail upon its can be provided with a label on each side during` its course through the machine. |The label is not only held down yieldingly on the surface of the can but it is wiped on and stretched out smooth by the action of the pad 52. At the Sametime the arcuate series of padsBG are arranged 1n stationary position so as to force the can against the pad with the label on the surface of the can which engages the pad, so as to help secure the above mentioned result. Thesepads are mounted on the ends of flexible bars which are capable of being twisted and bent to accommodate any irregularities in shape or position of the cans. The arrangement is such that the pads 36 are all stationary and rotate the cans by the revolution of the drum. rlhe air suction control is simple and effective. The automatic stopping of the device is of the simplest character while the starting of the machine is effected by introducing the can.

25. ln a labeling machine, the combination of a drum consisting of a pair of wheels or discs with a curved plate thereon, means for holding the curved plate loosely to permit a slight motion radially and circumferentially, a rubber pad located over the surface of the plate to receivev the label and apply `it to the article, said plate having a bracket on the'inner side, va lever pivoted o n the drum and having an end adapted to engage the bracket and a roller on the other end, a stationary cam in position to engage the roller once during each rotation of the drum and swing the lever to force the plate with its pad backwardly and outwardly, and

yielding means Vfor returning the plate to f its forward position.

26. In a labeling machine, the combination with a rotary labeling disc having two arcuate pads around its circumference for receiving labels thereon, of two label holders both arranged in such positiony that their top labels are substantially tangent tothe surface of the labeling drum, means connected with said drum for operating both label holders when the two plates come into registration with them at their forward ends, said operation of the label holders consisting in the lifting Vof the tops thereof to loosen the labels to allowthe top label to be picked o, means for gumming. the two labels one afteithe other as the drumA rotates, and means for bringing thetwo labels into contact with the opposite sides of an article to be labeled so as to place two labels around the article opposite each other. i

27. In a labeling machine, the combinai tion with alabeling drum rotatableon its own axis and having two arcuate pads on its circumference, one adjacent to the other, for receiving two separate labels, of a pair of label holders arranged with their top labelstangent to the drumand inposition to'engage respectively lthe two curved surfaces of said pads, a fixed cam, and means operated by the cam for operating both of the label holders when the drum rotates tol a certain point, to loosen the labels and allow the `top labelto be taken oil of each label holder by one of said pads.

28. In a labeling machine, the combination with a rotary drum,'of a curved series of flexible bars arranged concentric with the drum at a distance therefrom to receive the articles to be labeled therebetween and cause the articles to be rolled along the surface of the drum, said bars being held along their centers so that their ends are free to yield and twist to accommodate irregularitics in the articles and having soft pads on theirends for engaging said articles.
